Baiacu é uma das vinte e quatro espécies deste atlas. Não é um catálogo: evolução, anatomia, comportamento, cultura, ícones, conservação e área formam um só sistema.
As pontuações comparam velocidade, inteligência, área, resiliência, impacto cultural e papel ecológico. São juízos editoriais relativos, não um ranking de laboratório.
Sete capítulos aprofundam: origens, corpo e sentidos, vida e comportamento, cultura, ícones, pressão de conservação e a área partilhada com as pessoas.
Introdução profunda
Deep dive: Baiacu
Baiacu is not a single postcard animal. It is a set of populations, subspecies and human rules inside the fish family of this atlas.
Diversidade, corpos, cultura e áreas — mais uma lente desta região linguística.
Diversity inside the type
Field guides collapse many lineages into the English word Baiacu. Subspecies, flyways and captive lines do not share one fate -- bald eagles and Philippine eagles, or western and mountain gorillas, are the caution.
This atlas picks a Wikipedia title as the hero image and then keeps the rest of the grade in view so a recovered stock cannot launder a CR cousin.
Life in the landscape
A rigid boxy body, four fused tooth plates and a stomach diverticulum for inflation. Skin may carry spines; liver and gonad may carry TTX.
Crushing molluscs, crustaceans and reef invertebrates. Inflation is a rare expensive defence, not a commute gait.
Culture and meaning
English-language culture met the Baiacu through film, law, heraldry and zoos. Those portrayals move money and sometimes take; they are not a field census.
The culture chapter dates posters and statutes so a 1975 film or a 1961 logo cannot pretend to be a 2020s Red List.
Conservation and money
The family is mixed; fugu fisheries are regulated more as toxin law than as a single Red List story.
Tourism, conflict payments, quotas and captive loans are dated economic bands in the market chapter -- not live prices and not a best-species prize.

Biology deep dive: Baiacu
Baiacu biology is a stack of structure, energy, sensing and hard limits. The four sections below are the same headings used across the atlas so types can be compared without a best-species frame.
Anatomia, sentidos, comportamento e limites — mais a linguagem de campo desta região.
Structure
A rigid boxy body, four fused tooth plates and a stomach diverticulum for inflation. Skin may carry spines; liver and gonad may carry TTX.
Load paths and tissues (not metals) are expanded in the anatomy chapter.
Energy and foraging
Crushing molluscs, crustaceans and reef invertebrates. Inflation is a rare expensive defence, not a commute gait.
The how-it-works diagrams reduce that budget to a six-node loop.
Senses and control
Good close vision for a beak strike. Toxin is not a sense -- it is a stored consequence of diet and microbes.
Control here means the animal steering itself -- not a vehicle ECU.
Limits
A licence and a sodium channel. Over-harvest of Takifugu and reef heat are quieter than the poison story.
Resilience scores encode those limits relative to the other 23 types.
Four other atlas types, six terms, three threads and three local notes -- a map out of the Baiacu page without leaving the 24-id taxonomy.

Termos-chave
Tetrodotoxin
TTX -- a sodium-channel blocker concentrated in liver and ovary, often via symbiotic bacteria.
Fugu
Japanese puffer cuisine; licensed chefs, not a home experiment.
Takifugu rubripes
Tiger puffer -- the 2002 compact-genome model.
Inflation
Water (or air) pumped into a diverticulum -- a sudden sphere that jams a mouth.
Beak
Four fused tooth plates that crush molluscs and barnacles.
Puffer licence
Japan food-safety credential after Meiji- and postwar poisoning scandals.
Habitat and movement
Where the Baiacu breeds and feeds is the first constraint. Single lakes, islands and forests appear again in the history timeline.
Range scores in this atlas mark how widely that movement runs -- albatross and blue whale high, koi and panda low -- not a quality ranking.
Research and law
Named projects (Project Tiger, ACAP, ICCAT, Amboseli) are the English-language bureaucracy of the type.
Listings and downlists are dated events in the timeline, not eternal essences.
Culture and price
Film, auction and logo years are filed under culture and market so they cannot masquerade as demography.
The icons chapter keeps eight real Wikipedia titles so a later language pack can attach the same faces.
